Short Term Scientific Missions

The Honourable Schoolboy 






Dear CA18108 participants,

A new call for Short Term Scientific Missions is now open. Deadline for the applications is 23rd January 2023

The document of the call can be found in our usual web page:

This time I did not attach the document of the call, as last time there have been problems with sending attachments to many addresses so that finally many people did not get it. Please forward this information to your colleagues participating in the action (in case there may be problems with the e-mail list), especially young researchers, and do not hesitate to contact me in case of any questions. 

Best regards,

Dijana Dominis Prester (on behalf of the STSM Committee)

Special Issue Information

Dear Colleagues,

Noncommutativity is a long-standing subject in mathematics and physics. The proposal of noncommutativity in spacetime was first put forward by Snyder. 

In addition, noncommutative field theory has also been established. Substantially further motivations for investigating the noncommutative proposals have arisen due to the advances in string and M-theory and interesting predictions made in particle physics such as predictions about the IR/UV mixing, non-locality, Lorentz violation and new physics at very short distance scales. 

Several noncommutative gravitational scenarios have been inspired by noncommutative field theory. Noncommutative cosmology is also an application of noncommutativity between fields. More specifically, noncommutative deformations modify the noncommutative fields, and the effects of non-commutative gravity could be determined by applying mini-superspace variables. 

Such procedures have been constructed by employing the Moyal product of functions in the Wheeler–DeWitt equation as well as the semiclassical approximation of quantum gravity. In addition, classical noncommutative models have been studied by modifying the Poisson brackets.

Noncommutative cosmological models have been employed to describe various aspects of the universe, such as inflation, dark energy and dark matter. As already mentioned, UV/IR mixing is one of the features of noncommutative field theories, by which short scales are effectively mixed with long scales. Therefore, the noncommutative effects could be seen in the current time of the Universe due to the presence of noncommutativity effects at small scale. In analogy to the usual quantum mechanics, the noncommutativity effects are usually related to a minimal size by a generalized uncertainty principle.

Any review and further developments of the noncommutative proposals mentioned above that are relevant to gravity and cosmology are the focus of this special issue and are welcome.

Please read the following with care and in detail 

INSTRUCTIONS FOR STUDENTS

Submission of applications by students – 15th December to 27th January 2023, 17:00 (Lisbon time).

Before applying, and if you have never registered as a student in the IDPASC website, you need to register using the following link: https://idpasc.lip.pt/register

Applications can only be submitted electronically through: https://idpasc.lip.pt/pt_cern_grants

No other means of submission are available. Each applicant may submit only one application, under penalty of cancellation of all applications submitted. Due to the existence of non-Portuguese speaking members on the evaluation panel, applications should be submitted in English in order to ensure an accurate assessment of all the elements.

Providing false declarations or committing acts of plagiarism by applicants leads to the exclusion of the application without prejudice of taking other corrective and punitive disciplinary measures.

All applicants have access to the proposed thesis themes in the website https://idpasc.lip.pt/pt_cern_grants/phd_programme/call/18/thesis_proposals. Applicants should consult the proposed thesis themes and contact the supervisor/co-supervisors of the thesis. A communication between candidates and supervisors is mandatory. The work plan resulting from this interaction should contain a detailed description of how the goals of the research project will be achieved. The description should also provide all the necessary elements to allow the assessment by the evaluation panel, namely the methodological approach, description of tasks, their interrelatedness, sequence and schedule.

It may also include a contingency plan, addressing how possible unforeseeable difficulties might be overcome. In order to enable the Evaluation Panel to analyse the feasibility of the proposed work plan, a timeline with milestones for the different tasks should be included, showing the scheduling of the tasks proposed in the work plan, as well as the main milestones to be achieved, including the thesis submission (or the scientific work leading to the doctoral degree) at the university.

Once the topic has been selected by a candidate in agreement with the supervisor, the candidate formalizes his application by filling the Candidate Application form (provided on-line) and uploading the following documents (mandatory):

•    One CV file in PDF format, clearly and succinctly identifying the most relevant elements of your academic and professional career, such as academic and complementary training, scientific publications, communications at conferences, participation and organization of events, awards and other situations considered relevant for the CV assessment;
•    One Motivation Letter file in PDF format, explaining the reasons for her/his application, presenting her/his academic/professional career path and how it is related to the work plan, if applicable; in this field the choice of the most representative document should also be mentioned and justified;
•    The most representative document of the applicant’s scientific/professional path as, for example, a scientific publication, conference communication, scientific report or master thesis; proof of scientific or professional achievement, performances or artistic creations. Academic degree certificates, CVs or documents describing the applicant’s career path should not be submitted in this field;
•    One PDF file containing certificates of all the academic degrees obtained (Bachelor and Master), with the final average grade and marks in all subjects. The minimum grade of zero (A1 = 0) will be scored to sub-criterion A1 when no certificate is submitted, in the application form;
•    One PDF file containing the academic degree recognition and conversion of the final grade to the Portuguese grading scale or the presentation of the recognition/equivalence, registered by a public higher education institution. The minimum grade of zero (A1 = 0) will be scored to sub-criterion A1 when no certificate is submitted, in the application form;
•    Timeline, showing the scheduling of the tasks proposed in the work plan, as well as the main milestones to be achieved, including the thesis submission (or the scientific work leading to the doctoral degree) at the university;
•    Two contacts (names and e-mail addresses) for reference letters, excluding letters from supervisors.
(The reference letters will be directly uploaded by the referees. Applicants will not have access to the letters but they will be able to check if and when they have been uploaded. The referees will receive an e-mail with the name of the applicant and with a link for uploading their letters. The Referees can upload the letters during the whole period of the Call).
•    Optional PDF file containing other documents that the candidate may consider relevant for the assessment of the merit mentioned in the CV.
Besides of other factors, the final locking and submission of the application depends on the association of the supervisor and co-supervisor(s) (when applicable) to the application. The supervisors can only associate each thesis proposal with a single student.

Click “Associate Supervisors”. An e-mail will be sent to the applicant and to the supervisor, as well as to the co-supervisors (when applicable). Applicants must then be confirmed by the supervisor and co-supervisors (when applicable). They will need to fill the supervisor form (provided on-line), describing their personal judgment as regards to the student´s CV and his adequacy to the PhD subject.

After the supervisor and co-supervisors have locked their association to the application, applicants should click "Submit and Lock". At this point, the entire application will be validated and, if there is no error, locked.  No further modification will be allowed.

Academic degrees

Applicants with academic degrees obtained in Portugal must comply with the following, depending on their specific status:

•    For post-Bologna academic degrees, applicants should specify the final grades obtained in the 1st and/or 2nd study cycles, as well as the corresponding ECTS;
•    In case of integrated master degrees, for which the institutions do not provide separate final grades for the 1st and 2nd cycle of study, just the final grade and the total number of ECTS should be specified;
•    For pre-Bologna academic degrees, applicants should indicate the grades obtained for the graduate and/or master degrees.

For each of your academic degrees, you should click on the “Add Academic Degree” button, then select the respective option from the drop list and fill in the respective mandatory fields.

Important notice for national and foreign candidates

Only candidates who have completed the cycle of studies leading to a Bachelor's or Master's degree by the end of the application period will be admitted. Candidates who do not yet have their degree certificate may present a declaration of honor, stating that they have completed the necessary qualifications for the purposes of the call by the end of the application deadline.  

In order to comply with the foreseen applicable Portuguese legislation regarding the recognition of foreign qualifications, all the rights inherent to academic degrees granted by foreign higher education institutions is duly recognised to the holders of these degrees. This recognition is subject to the presentation of the academic degrees recognition and conversion of the final grade to the Portuguese grading scale, requested to the Dean of a public Portuguese University, the Head of a Public Polytechnic Institute or the Director-General for Higher Education; or by the presentation of the recognition/equivalence, registered by a public higher education institution.

The granting of the scholarship will depend on the presentation of all the documents. For candidates with diplomas issued by foreign institutions the academic degrees recognition and conversion of the final grade to the Portuguese grading scale or the presentation of the recognition/equivalence will be required for the granting of the scholarship.

Nevertheless, the presentation of degree certificates (national and foreign) in the application form is determinant for evaluation purposes, namely to calculate the score of A1, a sub-criterion of the Merit of the Applicant.

In case of academic degrees obtained abroad, only degrees with the respective records of recognition/equivalence and conversion to the Portuguese grading scale will be considered to calculate the score of A1 sub-criterion. The declarations of honor will not be considered for evaluation purposes.

The minimum grade of zero (A1 = 0) will be scored to sub-criterion A1 in the following cases:

a)    When no certificate is submitted, in the application form, neither graduate nor master’s degree certificates (national or foreign);
b)    When both national graduate and master certificates do not state the respective final grade (neither quantitative nor qualitative);
c)    When both foreign graduate and master certificates are not recognized, nor the final grades converted to the Portuguese grading scale.

The members of the panel will only assess the degrees duly recognized at the date of the application submission.

The legal regime applicable to the recognition procedures is approved by the Decree-Law no. 66/2018, of 16 August, if requested after 1 January 2019. For requests submitted before 1 January 2019, the applicable legal procedure is ratified by Decree-Law 341/2007, of 12 October, and regulated by Decree no. 227/2017, of 25 July, or, alternatively, for equivalence processes, the request is governed by the Decree-Law no. 283/83, of 21 June.


For further information, applicants are advised to carefully read Decree-Law 66/2018, of 16 August, and to visit the website of the Directorate General for Higher Education (Direção-Geral do Ensino Superior, DGES): https://www.dges.gov.pt/en/pagina/degree-and-diploma-recognition?plid=1536


Applicants with foreign academic degrees should:
- Indicate that the academic degree was completed abroad;

- Upload the recognition/equivalence of the academic degree and the final grade conversion to the Portuguese grading scale, issued by a Portuguese public higher education institution or by the Directorate General for Higher Education (DGES).
